Privacy-First, Offline PDF Tools

Amendly PDF Studio is built from the ground up for absolute file security and compliance. Unlike traditional online PDF editors that require uploading sensitive documents to external servers, Amendly does everything directly on your local device.

🔒 100% Client-Side Processing

All document rendering, editing, merging, splitting, and conversions occur inside your web browser sandbox using local WebAssembly binaries. Your files never touch our servers, keeping your private data safe.

📶 Works Completely Offline

Because Amendly is a Progressive Web App (PWA), you can disconnect your internet and continue working. Add text, crop, stamp, or compress PDFs anywhere, even on a plane.

Frequently Asked Questions

Are my PDF documents safe?

Yes, absolutely. Because the tools run 100% locally in your browser, your PDF documents are never uploaded to any server or network. They remain strictly on your local computer or mobile device.

How can a PDF tool work offline?

Amendly bundles core parsing engines like PDF-Lib, PDF.js, and specialized WebAssembly plugins directly in the app. Once loaded, the browser processes all bytes locally without any server-side dependencies.

Do I need to sign up or pay?

No. Amendly is completely free to use, requires no registration, and has no advertising trackers. We keep the service alive through user support and voluntary donations.
